Özet
Objective: To uncover the positional relationship between the lateral pterygoid plate (LPP) and foramen ovale (FO) in an adult population. Methods: The 500 normal subjects (250 males and 250 females), who underwent cranial computed tomography scans were included into the study. Results: Four configurations regarding FO location types were determined: the lateral type in 347 sides (34.7%), medial type in 115 sides (11.5%), the direct type in 412 sides (41.2%), and the far type in 126 sides (12.6%). The frequencies of these types were affected by sex (p < 0.001), but not side (p = 417). The most common configuration was the direct type (47.4%) in females and the lateral type (41.8%) in males. The antero-posterior and medio-lateral diameters of FO were measured as 7.35 ± 1.98 mm and 4.08 ± 1.26 mm, respectively. The antero-posterior diameter was greater in the lateral type compared to the medial and direct types (p = 0.003). The medio-lateral diameter was greater in the lateral type compared to the direct type (p < 0.001). The pterygoalar and pterygospinous bars were observed in 24 sides (2.4%) and 18 sides (1.8%), respectively. The positional relationship between FO and LPP was statistically different between presence and absence of the pterygoalar bar (p = 0.001), but not between presence and absence of the pterygospinous bar (p = 0.512). In FOs with the pterygoalar bar, the far type was seen significantly less common. Conclusions: The incidence of the far type was 12.6%; thus, a neurosurgeon can reach FO relatively easily by tracing the base of LPP backward in more than 80% of the population.
